Construction of a Digital Data-Logging Static Friction Coefficient Experiment Set Using Arduino for High School Hands-On Activities

Abstract This study discusses how to design and build a digital data-logging static friction coefficient experiment set using Arduino for high school practical applications. The apparatus includes an MPU6050 tilt sensor for exact angle measurement, a PIR motion sensor for precise motion detection, and an LCD display with real-time information. The study was through an R&D prototyping phase that the system was conceived. To make sure that the tilt data stays constant when the sensor is not moving, the calibration technique uses the “mpu.calcOffsets()” function from the MPU6050_light library to eliminate sensor bias. Three media experts gave the device an average score of 91.39% on six different criteria, recommending it was “very feasible.” The modular inclined plane has adjustable surfaces including wood, acrylic, and sandpaper. This Arduino-based sensor program will help make data more accurate, encourage inquiry-based learning, and get more students involved. More sensor settings, the ability to share data wirelessly, and the ability to measure kinetic friction are all possible future improvements that might make it more useful for learning.
